Question 3' CGGUAU 5' This is a short section of mRNA. Which DNA code probably produced this section of RNA? a. 3' GCCTUT 5' b. 5' GCCAUT 3' c. 3' ATTGCC 5' d. 5' GCCATA 3' Answer: D

Question Which of these represents the DNA segment from which this section of mRNA was transcribed? a. ACTAAG b. TCUTTG c. GAAUCU d. UCCTGA Answer: A

Question The diagram shows how an mRNA molecule is synthesized. What would be the most likely result if a bacterial infection stopped the production of the RNA polymerase? a. A protein could not be manufactured. b. A lysosome would digest the cell. c. Osmosis would not occur in the cell. d. Dehydration could be prevented in the cytoplasm. Answer: A

Using the codon chart, transcribe the RNA nucleotide sequence below: Question Using the codon chart, transcribe the RNA nucleotide sequence below: UUCACGGAAUGG UUC – phenylalanine ACG - Threonine GAA – Glutamic Acid UGG - Stop

Question RNA is used to code for proteins during the process of — a. replication b. transcription c. translation d. osmosis Answer: B

Question Translation (protein synthesis) takes place in a cell at the – nucleus mitochondria ribosome cell membrane Answer: C

Question 1 The assembly of a messenger RNA strand that normally begins with UAC has been changed so that the newly assembled messenger RNA strand begins with UAG. Which of the following will most likely occur? A The protein will be missing the first amino acid. B The amino acids that make up the protein will all be different. C The mRNA will become attached to a ribosome. D The production of the protein will be stopped. Answer: a; solute dissolve more quickly at higher temperatures.

Question 2 The diagram above shows chromosomes in a cell undergoing cell division. If one of the chromosomes breaks during this process, which of the following will most likely happen? A Mutation B Selection C Duplication D Segregation Answer: a; solute dissolve more quickly at higher temperatures.

Question 3 The diagram shows three generations of cells produced by a single cell through mitosis. In the process, a single mutation occurred at the point indicated. The mutation caused changes within a dominant allele. How many of the 15 cells contain the mutation? Answer: a; solute dissolve more quickly at higher temperatures.
